Bring a pot of water to boil.
Add a pinch of salt to the water and then your pasta. See my tips on cooking pasta.
When the water comes to a boil, add your pasta, stir immediately and cook to al dente. Be sure to stir frequently to prevent the pasta from sticking.
While the pasta is cooking, heat a saucepan over medium-high heat and squeeze the sausage meat out of the sausage skin into the saucepan. Break it up with a wooden spoon into bite size pieces. Brown the sausage meat until cooked through.
Add the tomatoes and cook with sausage meat for a few minutes. Add the olive oil and stir to coat the meat and tomatoes. Season with a little salt & pepper. Cook for an additional minute or two.
Drain the pasta and add some of it to the saucepan. It is easier to add more pasta if you have enough sauce than take it away if you don't have enough sauce. It really doesn't matter because the sausage and tomatoes are going to give the olive oil a lot of flavor and the oil should coat a decent amount of pasta.
Serve the pasta topped with freshly grated Parmesan cheese.
